Ukraine has received more than 50,000 rounds of 20-mm ammunition from Denmark for the onboard cannons of its F-16 fighter jets, with Ukrainian pilots already using the rounds to intercept Russian jet-powered Geran attack drones, Ukraine’s Defense Ministry said.

The accelerated delivery addresses a key need in Ukraine’s air defense as Russia increasingly deploys faster jet-powered drones that challenge conventional interceptors. Ukraine has also relied on F-16 cannons when stocks of air-to-air missiles are limited, making ammunition supplies important to keeping the aircraft effective against incoming aerial threats.

Denmark responds to ammunition request

The Defense Ministry thanked Denmark for responding quickly to Ukraine’s request for additional ammunition, saying the delivery directly strengthens the country’s air defenses and helps protect civilians from Russian aerial attacks.

The delivery follows a broader effort by Ukraine’s European partners to replenish F-16 cannon ammunition. On October 2, it was reported that Spain, Belgium, and Poland were also sending 20-mm rounds for Ukrainian F-16s to counter Russia’s jet-powered drones.

Belgium is also expanding its support for Ukraine’s F-16 fleet. On 16 October, Belgian Prime Minister Bart De Wever pledged to deliver 10 F-16s by the end of 2026, up from three previously planned, and discussed supplying additional ammunition, including 20-mm rounds produced by Belgian defense company FN Herstal.

Jet-powered drones pose a growing challenge

Russia’s faster attack drones are harder to intercept than older, propeller-driven Shahed-type models. Their speed gives air defenders less time to respond and makes them more difficult for many interceptor drones and conventional short-range weapons to catch.

Ukraine’s air-to-air missile shortages have also increased the importance of F-16 cannon ammunition. Ukrainian pilots have sometimes relied on their aircraft’s built-in 20-mm cannon when air-to-air missiles are scarce.

The threat from jet-powered drones is growing. Ukrainian President Volodymyr Zelenskyy said in late September that Ukraine was intercepting about 55% of Russia’s jet-powered drones, compared with more than 90% of older models.

Denmark’s ammunition delivery gives Ukrainian F-16 pilots more rounds to engage these faster targets, as Ukraine works to strengthen its defenses against Russia’s expanding drone campaign.
